Second one, Cellular Skin RX
Composition L-Ascorbic Acid 12% Butylene Glycol This one has its pros and cons. this time (I have to tell you that I've never used it. I've never seen a sample of the product itself.) - LAA 12% concentration is a lot, but 15% of Skinceutical without irritation. It's definitely more to my heart
- Using Butylene Glycol as a base (meaning that you have to put in a high amount) may cause irritation. There are studies from many institutions confirming that various glycol substances such as Butylene Glycol, Propylene Glycol should not be used in large quantities. Because it will irritate - inexpensive, selling abroad, 30ml at USD38 or about not more than 1200 Thai baht (if talking about the cost, it's still very expensive, 150 baht, but if compared to other cosmetics that give the same effect This price is considered inexpensive. The reason for using Butylene Glycol as a base instead of water (water-base) is because Cellular Skin RX doesn't have a technique like Skinceutical to stabilize L-Ascorbic Acid, so we refrain from using water as an ingredient. Of course, the life of the product will be longer than that of Skinceutical, of course, because it does not contain water to cause oxidation, but it lacks Vitamin E and Ferulic, which have been said to help increase the power of Vitamin C a lot (not in terms of oxidation. white skin But it's about skin rejuvenation (anti-aging / anti-oxidant)
